Rebex HTTP problem with other libraries

Hi
I have a problem using Rebex HTTP in combination with other libraries, eg RestSharp

after registering the creator like your sample:

var creator = new HttpRequestCreator();
creator.Register();

I got an error on each request with RestSharp (eg RestClient.Execute):

could not cast "Rebex.Net.HttpRequest" to "System.Net.HttpWebRequest"

Is there a workaround to solve this problem? or are other libraries not compatible your extension?

Regards Gerhard
